Abstract
A highly fluorinated benzene compound is reacted with acryloyl chloride to ield a fluorinated liquid product which is used to impregnate a reinforcing structure. Upon impregnation, the liquid material is polymerized at about 55.degree. C. to produce a reinforced polymeric structure, which can be a circuit board. The polymer has dielectric constant of about 2.1, which is very low compared to the polymers used presently.
